18 Mbit synchronous SRAM — 133 MHz, 1M x 18, 100-TQFP
The CY7C1383D-133AXCT: The parallel memory interface and synchronous pipeline make it a direct fit for high-throughput cache, buffer, or look-up table applications in networking and telecom line cards.
No pin-compatible direct replacement from Infineon is listed. The 100-TQFP footprint and 3.3 V supply rail mean a board spin is required if migrating to a different memory family — no drop-in alternative exists.
